Golang program to find the second largest elements from the array

Program/Source Code:

The source code to find the second largest elements from the array is given below. The given program is compiled and executed successfully.

// Golang program to find the second largest elements
// from the array

package main

import "fmt"

func main() {
	var large1 int = 0
	var large2 int = 0
	var arr [5]int

	arr[0] = 64
	arr[1] = 34
	arr[2] = 77
	arr[3] = 43
	arr[4] = 21

	large1 = arr[0]
	for i := 1; i <= 4; i++ {
		if large1 < arr[i] {
			large2 = large1
			large1 = arr[i]
		} else if large2 < arr[i] {
			large2 = arr[i]
		}
	}
	fmt.Println("Second largest element is: ", large2)
}

Output:

Second largest element is:  64

Explanation:

In the above program, we declare the package main. The main package is used to tell the Go language compiler that the package must be compiled and produced the executable file. Here, we imported the fmt package that includes the files of package fmt then we can use a function related to the fmt package.

In the main() function, we created and initialized an array of integers. After that, we found the second largest element from the array and printed the result on the console screen.
